TVOC concentrations measured in Belgium dwellings and their potential for DCV control

Over the last decade, TVOC sensors have been touted as an interesting alternative to CO2 and RH sensors in DCV systems. Nevertheless, there is little evidence on the nature and the profile of TVOC concentrations in modern dwellings. In this project, metal oxide TVOC sensors were installed in the local exhaust ducts in 3-4 bedroom low energy social housing dwellings equipped with a DCV exhaust ventilation system in Belgium. The TVOC and CO2 concentrations as well as RH levels were measured during operation and 2 control strategies were compared: the DCV was controlled based on the measured CO2... Mehr ...
